IEC 62458:2010(E) applies to transducers such as loudspeaker drive units, loudspeaker systems, headphones, micro-speakers, shakers and other actuators using either an electro-dynamical or electro-magnetic motor coupled with a mechanical suspension. The large signal behaviour of the transducer is modelled by a lumped parameter model considering dominant nonlinearities such as force factor, stiffness and inductance. It defines the basic terms and parameters of the model, the methods of measurements and the way the results should be reported. It cancels and replaces IEC/PAS 62458 published in 2006. It constitutes a technical revision. The main changes are: - descriptions of the methods of measurement are adjusted to the state of the technology; - addition of Clauses 4 to 15; - integration of Annex A in the main body of the standard; - overall textual review.
